The challenge by manager Walt Weiss could have been simply to give Lyles a short break.
Lyles gave up Yonder Alonso's one-out solo home run and consecutive doubles to Jedd Gyorko and Yasmani Grandal during the inning. He trailed, 1-0, and the Rockies prevented another run when center fielder Drew Stubbs and second baseman DJ LeMahieu made pinpoint throws to erase Gyorko at the plate on Gallardo's double off the center-field wall.
After the brief replay review, Lyles ended the inning by forcing Alexi Amarista to ground out.
